Chihuahua

The Chihuahua is the smallest breed of dog in the world and is named after the state of Chihuahua in Mexico. Both folklore and archeological finds show that the breed originated in Mexico. The most common theory and most likely is that Chihuahuas are descended from the Techichi, a companion dog favored by the Toltec civilization in Mexico.

Historical records indicate that the Techichi, were thought to hunt in packs. They can only be traced as far back as the ninth century but it is highly likely that this is the Chihuahua's native Mexican ancestor. Evidence of this is that the remains of dogs closely resembling, but slightly larger than the average Chihuahua have been found in such places as the Great Pyramid of Cholula, which dates back to the 2nd century BC and predates the 16th century. There is also evidence to suggest that the Techichi may also predate the Mayans.

A progenitor of the breed was reputedly found in 1850 in old ruins near Casas Grandes in the Mexican state of Chihuahua from which the breed gets its name.^[2] The state borders with Texas, Arizona and New Mexico where Chihuahuas first rose to prominence and were further developed in the United States. Since that time, the Chihuahua has remained consistently popular as a breed, particularly in America when the breed was first recognized by the American Kennel Club in 1904.
